Dun Dornaigil is an Iron Age broch in Sutherland. The broch has an external diameter of about 14.5 metres. The walls generally survive from 2 to 3 metres around the circumference of the broch, but above the doorway they rise to nearly 7 metres. The entrance is on the northeast side but is filled with debris. There is a massive triangular lintel over the entrance which measures 1.4 metres along the base, and 0.9 metres in height. The interior of the broch is still filled with collapsed rubble from the upper levels and is therefore not accessible.
References:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
